Patent number: 4855736Abstract: A parking sensor having a base for attaching to a vehicle, a flexible probe for contacting an impending obstruction, a contact for producing an electrical signal responsive to deflection of the probe, a lamp, buzzer, or other transducer for indicating the electrical signal, and a filter for preventing operation of the transducer during spurious occurrences of the electrical signal. The filter can include a timer for activating the transducer when the electrical signal continues beyond a first interval, which can be from 0.05 to 1.0 second. Also, the timer prevents activation of the transducer beyond a second, longer interval that is typically 10 to 40 seconds for terminating the indication (and power drain) when further corrective action by an operator of the vehicle is unlikely.Type: GrantFiled: June 3, 1988Date of Patent: August 8, 1989Inventor: Chi-Heng Hsu
